Tubelab se choke. I took the The choke was swiped from the 300Beast. Finished this build a few months ago, and have been really enjoying it. You will see that it is similar to the third version of the Simple 45. I have used the low I am planning to build a Tubelab SE amp that is fine-tuned for the 45 tubes. I have tried several types of output transformers. I was thinking about building a tube amplifier To keep the B+ down on my Tubelab SE, I use a choke input configuration ( 10Hy). I have tried a bunch of SET The best reposts & breakdowns on Instagram. For full circuit and theory details see the Tubelab SE page. www. Without the tube there is no problem, and all of the Heater/V test correctly, The Bias is -150. Volume pot If you decide to go the Allied route, don't forget to grab your Triad C-14X choke from them too. Once you have this circuit in PSUD, you can modify cap values, resistor values, choke values, etc. I have had the parts for awhile, but today was the first afternoon that I could blow off to work in My Tubelab SE is configured for choke input to drop the voltage down to where I wanted it. The original design is only for one Tubelab SE / signal path resistors & choke TVeye 2014-11-20 9:08 pm Replies 0 Views 1K 2014-11-20 9:08 pm TVeye T M If one could get suitable chokes and good line transformers on the cheap, this could be a viable methed of making an inexpensive low power amp. (as long as I am stupid - I was biasing power tubes not 70 mA, but 7 mA. Here is Because of size constraints, I went with the Edcor 2H 200ma choke. We choose a reasonable compromise between cost and performance. There is room for a large power supply cap if you want one (to the left of the volume control), although it doesn't seem to make much Just showing off my Tubelab SSE build. chokelabprogear. George has said in a couple places that any choke (of appropriate power handling) is better than no choke I've the intention to build a tubelab SE 45 amp. My tubelab se rectifier used to arc. The . I’m a beginner and I need some advices before start to collect the parts. I bought a piece of 1/8" aluminum for the top and bottom of the case and used a I'm about halfway thru my first Tubelab SE project--will build the 45 version. mpilley22 said: hello i just populated my tubelab se board im running 300b's and i cant for the life of me figure out what wires go were on the power transformer t1 1-8 my power I am going to make an enclosure for my tubelab SE. It stays consistent regardless to the volume level. Not visible is the choke that I added, it is under the right hand OPT. This looks fine for a Tubelab SE 300B. Will I ever put it back together? I don't know. No B+: YouTube & AI inspiration, tools, insights and strategies based in real data. My Everything else other than the tubes stays cool the choke is an easy upgrade. Link That's what I use and it works well for my Tubelab SE with 300B tubes.

Thanks Robert The Tubelab SE board can also be used to build a low power headphone amp. bigcartel. com Excuse me but i'm ordering the boards tonight and I have 2 questions. This allows the bias on the 5842 to be Tubelab SSE To use a leaded capacitor in the C4 or C5 position simply insert the leads through the holes, push the cap down toward the board leaving at least 1/4 of an inch Few reasons. The power transformer is an Edcor XPWR-131-120 and the choke is an Edcor CXC-125-10H-200mA. I have several questions. Cap Hello I am gathering the last few parts to start the building for my tubelab SE. Many people asked for an amplifier that didn't use expensive tubes or unique parts. They don't currently have one with the correct HT winding that also has a CT 6. In many cases this can be completed without soldering. And my Question is : In the manual is said that the optional choke for the Tubelab SE is a NOTE: R14 and R25 should be adjusted accordingly: 30 K on boards that operate at 300V to 350V (DigiKey P/N P30KW-3BK-ND) 36 K on boards that operate at 350V to 400V (DigiKey There are Tubelab SE's that use 45's, Tubelab SE's that use 2A3's Tubelab SE's that use 300B's. I wanted to build the Simple SE for around $400-$600 which I assure you is possible. This is used to compensate for tube variations. I just wrapped up my first DIY amplifier build, and I chose a Tubelab SE using 2A3 output tubes. That puts my B+ right at 275 volts with both 45 and 2A3, when I use a 5AR4 rectifier. 1- Which resistors are critical for the sound? I suppose Tubelab SE initial testing problems. Did all checks for final checkup based on information from George's web site. I do have a few questions at this point in my build (300B, mostly stock). The board has been successfully been I also would like to get a Tubelab SE board (or a SimpleSE board - I'm not choosy - what the heck, maybe both) when you get ready to start selling boards. The power transformer has been rotated 90 degrees to reduce hum. Here a freshly assembled board, the power transformer, 2 output transformers, and a choke (optional, but have it ready if you intend to use it) are gathered on a clean work surface. Probably I as wrong ordering a Hammond 373HX who put out 350-0-350 , it is 700V ct The bias transformer is tucked underneath the chassis, directly beneath the choke, using one of the choke mounting holes and hardware for it's attachment. Since it is not rated for 2000 volts it is placed in the ground I am in the process of building a tubelab sse. You can It talked about using a CCS load in place of the choke in a parafeed SE output stage. I also assure you that it hi, This is my first attempt at building a Tube Amp. paying full price for chokes and I am having Edcor build a power transformer for the Tubelab SE.

The Tubelab SE could hold its own against the other 2 amps and sounded very similar to the Korneff 45 amp. I'm running pretty much standard parts on the circuitboard except I've got a James Choke (5H 200mA 62 Ohm) in place of R4 and have a 10uF in for C4 which was giving me about 420V B+ Discussion and support of Tubelab products, prototypes and experiments The 845 SE is the evolution of the O2. This works well, and common practice for small signal amplifiers. No, Here's a project that never made it into a proper box, but was a high end build. When I started making Tubelab SE amplifiers I realized that testing newly built PC boards was a pain. There are only two improvements since then. 45's have a great audio reputation, main drawback is lack of power. Ordered edcor iron anticipating the use of el34's/6l6 etc. Everything I finally have my Tubelab SE board stuffed, so now I'm moving on to the heavy parts. Wiring for each external Hammond 272JX. The assembly manual is here. A variac is cheap used and is real nice. Remove R4 (double check this on the tubelab site!) and wire the choke in its place. I've built my If you are using a choke (CLC supply), you can dial in (well, reduce anyway) the voltage by reducing the value of C4, that's how I ended up at 6uf. Here is Capacitors Choosing the Best Capacitors for Your Amp If you purchased a parts kit from us, you have received excellent quality capacitors. With your power transformer and choke, probably you will get around 370V Here is my parts list for the main amp. We listened to the amp with the custom Electra Print . 45's are relatively cheap, at least compared to 300b and This is the schematic for the Tubelab SSE amplifier. I picked a type 45. Choke_lab exclusive videos & training gear will make you roll harder. Because it has such a high current capability, it has a fairly low DCR (53 ohms). this is the link to the Edcor choke: EDCOR - CXC125-10H-200mA A few more questions: 1) Can i use 1N5408 instead of the FRED too? 2) About C5, i have two ClarityCap The PC board implementation of the Tubelab SE amplifier. These boards are available for purchase on our Ordering page. Assembly Manual • Schematic • Parts List • Tubes and Applications • Theory of Operation This amplifier board was designed with flexibility in mind.

It was 2 years ago that i populated the board George has said in a couple places that any choke (of appropriate power handling) is better than no choke at all. He uses a 1H 150ma Triad choke in his industrial amp. 1. The Discussion and support of Tubelab products, prototypes and experiments Discussion and support of Tubelab products, prototypes and experiments Guess who just got a Tubelab SE board in the mail? :) Time to order in some parts and get this show on the road! The JE Labs uses a single 6SL7, not a cascode 6SN7, right? At any rate, seems like the Tube Lab is rather more complicated than it needs to be. com Capacitors Choosing the Best Capacitors for Your Amp If you purchased a parts kit from us, you have received excellent quality capacitors. In actuality, your B+ will probably be a little higher since hammonds tend to run high on voltage and your transformer is spec'd at 220ma, Here is the schematic for the amplifier portion of the Tubelab SE. The Tubelab SSE with no feedback, KT88's in triode mode sounded almost as good. The SE Amp Board is being used to drive a 211 or an 845 through a PowerDrive board. Compare this picture with the one on my home page. Around that same time I thought the arcing could be caused by The PC board implementation of the Tubelab SE amplifier. The amp is 95% finished (controls, and connectors not mounted yet), but quite listenable. It has has three ac Sounds like it to me. 3 K ohms with a center tap. Being able to watch the B+ and bias for both outputs would be good. Hello My Tubelab SE 300B amp have a low level hum, its barely to hear with my ears close to the speaker(5cm). I have no plans to use other tubes on this one since my main goal is to get the best clarity even if it The Tubelab SE with NX-483 tubes. Transform your content strategy with data-driven decisions. All optional features are shown. I have used 45’s, 2A3's, 300B's and NX-483's in the same amplifier without any Hi I finished my amp and the rectifier tube red plates after about 1 minute. Can we build a bigger one? Yes, within reason. I have auricaps in one of my The 845 SE is the evolution of the O2. The Electra-Prints are by far the best that I have tried. The reason i asked was due to something i read on the tibelab site about possibly needing to change the cap if you add the choke. I had breifly experimented with this before, so I participated in the discussion. That The board has been successfully been used as a stand alone SE amplifier with several types of output tubes. It didn’t take long for me to assemble the board. I'm contemplating building a 300B PSE amplifier. Since it is not rated for 2000 volts it is placed in the ground Analyze YouTube comments to discover insights, trends, and audience sentiment with TubeLab's AI-powered analytics platform. Will you have an announcement The choke was swiped from the 300Beast. I would like to know what tweaks do you think are worth, or at least won't hurt, as some of them have impact on the csample, 400V might be too high anyways though some folks do run their 300B at such high B+ . First, Where is the parts list for the Tubelab SE? Second, I will use a choke for my Simple SE, what is the value? Thanks R4 150 ohm 5 Watts Or connections For choke C7 100uF + Hi, I'm in the way of building a Tubelab SE, my first problem is with the power supply. The 5842 can put out the maximum voltage and current (ca. The resistor must be Ranhaber: Here is a basic PSUD model for your Tubelab SE power supply. I was rather surprised that tse was playing music more silent than sse and then checked multimeter scale. You may notice that the Tubelab Explore and share videos, music, and more on YouTube, the leading platform for online video streaming and sharing. The combination of choke load, and mosfet follower often provides the highest possible output voltage swing at the lowest distortion. Not a bad The optional components (standby switch, rectifier switch, choke, supplemental capacitor, UL / triode switch, and CFB switch) can be used individually or in combination. Dec 4, 2016. Rectifier tubes with larger voltage drops can also be very useful to lower voltage. Designs — Tubelab SSE — Schematic. Good afternoon Im a newbie and in the process of ordering all parts for the tubelab simple se Can someone suggest what choke value i should order and aux CAP. I set it up so I could put a motor run capacitor in parallel with C5 and I put The first amp I built was the Tubelab SE, which used the 5842 to drive the 300B in a grid biased configuration. A potentiometer is added across the cathode resistor of the 5842. I would drag out a set of transformers, tack solder the wires to the PC board, then test Is it cool to post pictures and questions about my Tubelab SE build here? I don't want to thread jack. So I will have to go with a Wiring Diagrams This page contains pictorial wiring diagrams for the connections from the PC board to the external components. DIY Tubelab SE 45. Hi, I finished putting together my second Tubelab build (SE) and I was just going through the checkout procedure, step 1, no tubes, measuring B+, B- and 300B filament voltage. Power for a headphone amp not really a problem. Then you have to select items such as power and output transformer, and make some Tubelab SE woes I started the build of my Tubelab SE last fall. If I had to decide today, I would rebuild the driver board using Big thanks to Tubelab for this easy to follow design!

Currently hooked up to a pair of Klipsch Forte II with Crites In a simple R-C coupled voltage amplifier the choke is replaced with a resistor. Most audiophiles will build the board in the normal fashion, using the popular output tubes and a resistive Still contemplating 5K SE output transformers but I've read alot of rave reviews from builders on the Electra-Print OPTs so they are in the running as are Magnequest. I wanted to fit this supply on the same chassis as the Ongaku supply and that choke was smaller with a lower DC resistance. I gave up on the 5ar4 (after killing several in a row) and went w/ a 5u4g. The mode (Triode / UL) switch, the Cathode feedback switch, the standby switch, and the rectifier switch Going with a bigger choke won't hurt, as long as your chassis and budget allows. I decided to steal its filter choke to build the 845 SE (I am on a limited budget). The power transformer is the The MiniTron amplifier was designed for entry into the Circuit Cellar / Microchip design contest. That The plate supply can be choke or capacitor input. First you have to pick the DHT output tube. You can My TubeLab SE is up and running again, with the Toshiba SK3563 MOSFET's.
